I'm attempting to add a method to a grails domain class, e.g.
class Item {
String name
String getReversedName() {
name.reverse()
}
}
When I attempt to load the application using grails console I get the following error:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory':Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property reversedName in class Item ... 18 more
It looks like Hibernate is interpreting getReversedName() as a getter for a property, however in this case it is a derived field and hence should not be persisted. Obviously in my actual code the business logic I'm exposing is more complex but it isn't relevant to this question. I want to be able to call item.reversedName in my code/gsps.
How can I provide property (getter) access to a method in a Grails domain class without Grails attempting to map it with Hibernate?
